According to CNN, prior to resigning, former White House staff secretary Rob Porter was up for a promotion. Citing multiple anonymous sources, CNN reported that Porter was actively lobbying to take on duties not typically assigned to the staff secretary, including assisting with policy rollouts and speechwriting. Porter was also attending high-level strategy meetings on trade, and may have been considered for the role of deputy chief of staff. One of the Trump administration officials who apparently supported expanding Porter's role was Chief of Staff John Kelly, who reportedly knew for months about the allegations of domestic violence that ultimately led to Porter's resignation. In testimony provided to the Senate Intelligence Committee, FBI Director Christopher Wray claimed that he first told the White House about the allegations against Porter in March of 2017, before following up with a completed background investigation in July. – CNN
